Mathematics Teacher

Faculty / Full-Time

Commonwealth School, Boston, MA

Full-Time Math Teacher

Commonwealth School, an independent day school that occupies two brownstones in Boston’s Back Bay, is known for its rigorous academics, low (5:1) student-teacher ratio, and strong program in the arts. In the warmth of a small yet richly varied community of engaged students and passionate teachers, talents and curiosity generate excitement, laughter, and respect among students, faculty, and staff. We work closely and collaboratively with each other in our cozy space, and we make extensive use of Boston’s many resources. 

Our mission is to educate young people from diverse backgrounds to become knowledgeable, thoughtful, and creative adults, capable of careful analysis, fruitful cooperation, and responsible leadership. In keeping with our mission, our teachers challenge and support students as they develop the skills that will encourage their lifelong love of learning. 

Our teachers design curriculum, reflect on their practice, create partnerships within their departments, and support student learning both in the classroom and in one-on-one tutorials. Faculty and staff value trust and respect, shared stewardship, autonomy, accountability, creativity, and enjoyment (see our fully articulated norms here). Detailed information about the school is available on our website

Position Description
We seek a full-time teacher for AP-level courses in Calculus and Statistics for the second semester (the end of January through the middle of June 2023). While this is only a semester-long appointment, it is possible that the position could become permanent.

Students arrive at Commonwealth with a wide variety of backgrounds. By graduation, all students have completed at least one year of calculus or statistics, and many go far further. We offer courses covering topics ranging from Algebra 1 and geometry through AP Calculus BC and beyond, including advanced electives in Linear Algebra and Abstract Algebra. You can read more about our math department and its curriculum here

Duties and responsibilities include the following: 

  • Teach two sections of Calculus 1 (a full-credit course that covers the majority of topics on AP Calculus AB exam), one section of a full-credit Statistics course, and one section of a half-credit Statistics course (AP). The full-credit courses meet four times a week for forty minutes, and the half-credit course meets twice a week for forty minutes.
  • Fulfill occasional duties beyond the classroom that are shared among the faculty and staff, including joining our all-school retreat in May (learn more here) and serving as a faculty advisor to our math team.

The 6-month salary is $28,000-$35,000 for those with up to 5 years of relevant experience and $38,000-$45,000 for those with 5+ years.


Firmly committed to establishing culturally responsive classrooms, we seek teachers who think independently and love learning, especially alongside high school students. Ideal candidates will possess a deep knowledge of their field and find joy in fostering students’ understanding of the subject. Candidates should have at least a bachelor’s degree in mathematics and some experience teaching; an advanced degree is preferable. The ability to teach economics or computer science would be a plus.

Ideal candidates will have demonstrated commitment to supporting equity and inclusion in a diverse community. They will have some teaching experience at the college or high school level, as well as a keen interest in collaborating with colleagues while mentoring young people. 

Interested candidates should email the following materials by Monday, November 28, to Dean of Faculty Hiring and Support Mara Dale ( 

  • A cover letter that describes their experience, teaching philosophy, and commitment to fostering inclusive classrooms and equitable outcomes for all students 
  • A résumé or CV 
  • The names of three references and their contact information
